The present invention relates to an electric steering wheel for a vehicle. The electric steering wheel for a vehicle includes: a housing; a worm shaft installed in the housing; a worm wheel installed in the housing and engaged with the worm shaft; a bearing rotatably supporting the worm shaft by being connected to one end of the worm shaft; and an anti-rattle unit installed on the outer side of the bearing. The anti-rattle unit includes: a first anti-rattle member mounted on the outer circumference of the bearing; a second anti-rattle unit arranged on the outer side of the first anti-rattle member by being separated from the first anti-rattle member, and mounted on the inner side of the housing; and an elastic member connecting the first anti-rattle member and the second anti-rattle member by being mounted on the first anti-rattle member and the second anti-rattle member and pressurizing the first anti-rattle member toward the second anti-rattle member by an elastic force. The electric steering wheel for a vehicle can prevent rattle noise and simultaneously prevent vibration and noise from occurring when the worm shaft moves.
